This bottle is very similar to one illustrated by Moss, Graham and Tsang in A Treasury of Chinese Snuff Bottles: the Mary and George Bloch Collection, Hong Kong, 2002, Vol. 5, p. 588, no. 956, where it is mentioned that the interior molded detail is 'to create the impression of a fabric pouch. Attributed to the Imperial glassworks, Beijing.' They go on to say that this group of bottles is 'an exceedingly rare type of bottle.'
